type casting:
   
   type casting is a phenomenon in java by which we can fit a value of a
   datatype into another datatype.It is of two types:
   
   
   1)Automatic type casting
   
   
   in this type,when we have to fit a lower datatype into a higher datatype,the
   system on its own does it.eg:
   
   
    int a=5;
   
   
   double b=a;
   
   
    
   
   
   2)Conversion type casting
   
   
   in this type,a higher data type is to be fitted in lower data type.it should
   be done manually.if not done so,we will get an error as 'possible loss of
   precision'.
   
   
   eg.:
   
   
   double a=5;
   
   
   int b=(int)(a);

   while actual parameters which are defined or stated by the user in a class
